SPRAYINGAND VAPORIZING DEVICE FOR CRUDE-OIL EXPLOSIVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 676,285, dated June 11, 1901.

Application filed March 17,1900. Serial No. 9,031. (No model.)

To aZZ whom it may concern.-

' Be it known that I, FRANK VAN DUZEN, a

citizen of the United States, residing at Marion, in the county of Marion and State of 5 Ohio, have invented certain new and useful 1oof explosive-engines using crude oil as a fuel.

The object of my invention is to provide an improved apparatus for heating the air and crude oil before mixing and then mixingthe same by a spraying device in the mixing-chamber located within the heater, the features of which are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which- Figure 1 is a top plan view of my improve- Fig. 2 is a section on line 00 00, Fig. 1. Fig. 3 is a sideelevation of Fig. 1. Fig. 4: is a modification of the valves and mixing device shown in Fig. 2. Fig. 5 is a central horizontal section on lines y y, Fig. 2. Fig. 6 is Fig. 7 is a sectional view on lines o '0, Fig. 2.

A represents an exhaust-pipe leading from the exhaust-valve of the cylinder located at A to the heating passages or jacket surroundo ing the mixer B.

- G G represent conduits which partially surround the miXing-chamber and through which the gases or products of combustion generated in the cylinder pass on their Way to the final exhaust port or pipe F, which is shown mounted on the top of the heater. The mixing-chamber is preferably of scroll form for convenience of construction and provided with air-jacket spaces I I for supplying air 4'0 to the mixer.

a represents orifices admitting the air into the outer jacket. I and b represent'orifices admitting air from the chamber I into the chamber or spacel. The air is heated by able guide R, as shown in Fig. 2. The exhaust-gases, pass from the passages G into the heater and sprayer, located in the top T, through ports H H H (shown by dotted lines, Fig. 1) into the annular space E, which is tapped by the exhaust-pipe F. l

U represents an oil-tank mounted upon the top of the mixer and receiving heat therefrom, whereby the oil is kept in a fluid condition, so as to freely flow from the outletpipe into the mixer.

0 represents a pipe leading from said oilchamber into the valve-chamber d, in which is located the oil-valve 13, provided with a stem S, which depends down through the valve-pipe a in juxtaposition with the valve R, which 'when said valve is raised by the suction of the piston comes in contact with the said stem and lifts the oil-valve, allowing the oil to flow down around said stem and to bedischarged from the mixer-nozzle e. The oil is still further heated in its passage to the nozzle.

-N represents an annular chamber formed in the mixer T, as shown in Fig. 2, and is supplied with air through the opening J, lead ing to the atmosphere.

In order to spray or split up the oil, I provide a series of small orifices 0, leading from the hot-air chamber N into the nozzle around the valve-chamber cl and stem S. These orifices are of small area, so that only a small portion of air necessary to carburet the oil is supplied through the same, the larger amount of carbureting-air being supplied by the valve R, which is automatically operated by the suction-stroke of the engine-piston. It will be observed that the air entering through the port 0 unites with and is mingled with the 1 oil as it passes out of the mouth of the nozzle 6 into the mixing-chamber B, where the oil is further carbureted by the air admitted around the valve R as it is lifted from its seat. These two currents-to wit, the upper one of the mixed-air'and oil and-the lower current of air-enter in opposite directions, and as they come in contact cause a whirl within the mixing-chamber, thereby obtaining an intimate mixture and a thorough carbureting of the oil as it is drawn forward to enter the cylinder through the receivingvalve D.

In themodification shown in Fig. 4 I provide an air-jacket f around the exhaust-pipe F and by pipe f supply the annular chamber N, thereby more efiectually heating the air supplied through the spraying-nozzle e. The

valve R in this'modification is provided with a cup '1', into which any oil that trickles down the stem S may pass and out of the orifices r around the base of the cup.

8 represents orifices pierced through the valve B, so asto admit air-current to assist in spraying the oil to insure a thorough and minute division of the oil, and hence an intimate mixture of the oil and air.

The oil-tank U is of course supplied by a gine, the mixer and oil-tank are preferably heated by a lamp or gas-burner until the oil and air are of sulficient heatto insure an intimate mixture of the explosive material, thus securing the initial explosion for starting the engine. The discharging of the hot gas from the cylinder maintains the heat in the mixing-chamber to secure the mixing and carbureting, heretofore explained, of the fuelgases supplied to the explosion-chamberof the engine.

Having described my invention, What I claim is-- 1. A heating and mixing device for an explosive-engine, consisting of an oil and air mixing chamber, one or more heating-chambers surrounding the same, connected respectively with the exhaust-pipe of the engine and a discharge-orifice, one or more airjackets surrounding said heating-chamber, a

valve between said air-jacket and the mixingchamber, an. oil-supply pipe, a valve in the same, having a discharge-nozzle into the mixing-chamber, an air-heating chamber communicating with said discharge-nozzle and means for actuating said air and oil valves, substantially as described.

2. A heating and mixing device for an explosive-engine consisting of an interior mixing-chamber, means for passing the exhaust products from the engine around the same, an air-heating compartment adapted to be heated thereby, an oil-supply pipe passing The mixing device mixing-chamber, substantially as specified.

3. A heating and mixing device for an ex plosive-engine, consisting of an interior mixing-chamber, a heating-compartment surrounding the same connected respectively with the exhaust-pipe of the engine and with the discharge-orifice, an air-heating jacket surrounding said heating-compartment, the said jacket having chambers under the mixing-chamber, an air-valve connecting said air chamber with the mixing-chamber, an oil'- supply pipe, a valve in said pipe adapted to discharge into the mixer, a heated air passage communicating with the mixing-chamber and surrounding saidoil-valve, the said oil-valve having a stem depending into the mixer and terminating above the air-valve whereby when the latter is raised, it will actuate the oil-valve, substantially as and for the purpose specified.

4. A heating and mixing device for an ex= plosive-engine consisting of an interior mixing-cham'ber, a heating-compartment sur rounding the same connected respectively with the exhaust-pipe of the engine and the discharge-orifice, an air-jacket surrounding the said heating-compartment and having a chamber under the said mixer, a valve be= tween the said air chamber and mixer, an oilsupply pipe, a valve therein having a dis charge-nozzle into the mixer, a secondary heating=compartment surrounding said oilpipe, orifices connecting said secondary air chamber with the said oil-discharge nozzle, and means for operating said valve, substantially as described.
